Behavior
Harmless to humans, these lizards are known to run from potential threats. When disturbed, the Chuckwalla will gulp air, distend its body and wedge itself into a tight rock crevice. The Chuckwalla will inflate its body with air in order to entrench itself.
Males are seasonally and conditionally territorial; an abundance of resources tends to create a hierarchy based on size, with one large male dominating the area's smaller males. Chuckwallas use a combination of colour and physical displays, namely "push ups", head-hobbing, and gaping of the mouth to communicate and defend their territory (see animal communication).
Chuckwallas are diurnal animals and as they are exothermic, spend much of their mornings and winter days basking. These lizards are well adapted to desert conditions; they are active at temperatures of up to 102°F (39°C). Chuckwallas brumate during cooler months and emerge in February.
Mating occurs from April to July, with 5-16 eggs laid between June and August. The eggs hatch in late September.

Famous quotes containing the word behavior:
“I like to think of my behavior in the sixties as a learning experience. Then again, I like to think of anything stupid Ive done as a learning experience. It makes me feel less stupid.”
—P.J. (Patrick Jake)
“The fact that behavior is normal, or consistent with childhood development, does not necessarily make it desirable or acceptable...Undesirable impulses do not have to be embraces as something good in order to be accepted as normal. Neither does childrens behavior that is unacceptable have to be condemned as bad, in order to bring it under control.”
—Elaine Heffner (20th century)
“As long as male behavior is taken to be the norm, there can be no serious questioning of male traits and behavior. A norm is by definition a standard for judging; it is not itself subject to judgment.”
—Myriam Miedzian, U.S. author. Boys Will Be Boys, ch. 1 (1991)
